According to Agence France Press, drivers in Porirua, a town of about 60,000 people north of Wellington, have been loudly playing the singer's tunes as late as 2 a.m.
They have been cranking up the volume on the Canadian songstress's most famous ballads, including "My Heart Will Go On" and "It's All Coming Back to Me Now," according to AFP.
It's part of the "siren battles" trend that has been going strong in New Zealand for several years, which appears to be particularly popular with indigenous people from the Pacific Islands.
